its zero, I'm not too sure how I can explain this properly, but for horizontal lines, the slope is always zero

Dude just stop your only saying D so you can get the stupid medal but at this point idc about it I just want him to get the right answer!

formula to find slope \[\huge\rm \frac{ y_2-y_1}{ x_2-x_1 }\]
since the line is horizontal |dw:1443791506934:dw|
horizontal line when y is constant and x values are changing

u dont tell me wht to do redneckk and me too

let's say we have (2,3)(4, 3)( notice y values are the same )
plugin \[\frac{ 3-3 }{ 4-2 }\]
when you subtract same numbers what would you get
in this question 3-3 =?

remember the formula is = change in y's over change in x's

ok so im going with zero slope
thank you everyone
i'll tell you who's right a bit later and medal them

did you understand ???

yeah a bit
that helps with the rest of the questions i might have thank you

alright just practice
remember when we subtract same numbers we will get zero
so zero divided by anything would be just 0

ok got it :)

let's say if we have vertical line |dw:1443791845577:dw|
in this questions x value would stay the same

so when substitute points into the formula (3,2)(3,4) (x values would be the same ) \[\frac{ 4-2 }{ 3-3 }= ???\]

Nnesha

i'm pretty sure ur next question would be on vertical line slope

anonymous

yeah it is

2/0

i just picked two points but for vertical line x -coordinate would be the same 4sure

Nnesha

right so answer would be what
2/0 = ?

anonymous

0
so zero slope?

Nnesha

no no you can't divide by zero
whenever u get `0 at the denominator ` answer would be undefined bec you can't divide by 0

oh undefined ok bc thats what i originally thought

i knew there was some rule between the horizontal or vertical slope i just forgot which
